  • In this paper, the rst issue presented and analyzed by several experiments is the in- uence of the distance between phosphor layers in the dual-layer and triple-layer remote package on luminous ux and color rendering property. During the simulation, it was realized that it was possible to create a suitable distance to create higher quality white light-emitting diodes (WLEDs) by adjusting the distance between the phosphor layers.

  • This study proposed a triple-layer remote phosphor (TRP) structure to improve the color and luminous ux of white LEDs (WLEDs). TRP structure consists of 3 di erent phosphor layers: yellow YAG:Ce3+ layer below, red CaMgSi2O6:Eu2+,Mn2+ phosphor on top and green layer Ba2Li2Si2O7:Sn2+,Mn2+ phosphor in the middle.
